Question 496021: I am so confused as to how to answer this question.
Joe Bond, secret agent, rows 6 miles downstream in 1 hour to rescue a damsel in distress. When he finds her, she tells him that he must row back upstream the same distance to defuse a bomb set by the nefarious Dr. Fiendish. The bomb is timed to go off in 3 hours.... and Bond just barely arrives in time to defuse it. What is Bonds rowing speed in still water, and what is the speed of the current?
thank you

Question 496109: DIRECTIONS: Find the slope of a given line, if it is defined.
#5. The line through the origin and the point (-4,10).
*I know the formula for slope is.... m = y2-y1/x2-x1
*I know how to calculate the slope given 2 points
but am having difficulty determining the origin.

Question 496369: Project Overview
In this assignment, you will gather nutritional information for two different foods to devise a meal plan that provides optimal nutritional value.
Part I: Data Collection
To maintain health, people need to consume a recommended daily amount of many different vitamins and minerals, as established by government health agencies. To achieve those levels, people have their choice of many types of food to consume. For the sake of simplicity, assume that you are a poor college student who can only afford two items: broccoli and corn. Also assume that the only nutrients you absolutely need to maintain proper health are calcium and iron.
Gather from credible sources the following data:
•The amount of calcium and iron (in milligrams) found in one 10 oz package of broccoli
•The amount of calcium and iron (in milligrams) found in a ˝ cup of frozen corn
•The recommended daily values (in milligrams) of calcium and iron
Part II: Building the Meal
After collecting the data, it should be clear that one 10 oz package of broccoli and one ˝ cup of frozen corn will not allow a person to achieve the minimum levels of calcium and iron for one day. To that end, you need to determine how much of each food item you need in order reach those levels. Construct and solve a linear system of two equations that would make that determination.
Part III: A More Realistic Meal Plan
Naturally, people need more than two minerals to survive. Likewise, people eat more than just broccoli and corn. Find four more essential vitamins and minerals and their recommended daily values (in milligrams). Likewise, find four more foods that contain each of the six vitamins and minerals you have listed. Determine that the amount of each nutrient found in one serving of each food.
Using that information, construct but do not solve a linear system of equations that determines how much of each item a person would need to consume to achieve the recommended daily values of each nutrient.
Part IV: Reflection
Write a statement reflecting on your appreciation for algebra and how it can be applied to a real situation. Support your statement with examples of applications.
Refer to the Course Schedule within the Syllabus for specific project deliverables and due dates.
Deliverables
•A linear system of two equations, constructed and solved (from Part II)
•A linear system of equations, constructed and not solved (from Part III)
•A reflection statement with examples ( Part IV).
Timeline
•Week 6: You will complete Parts I and II described above in the Project Overview section. This Week 6 deliverable will be graded with the "A Linear System of Two Equations (Part II)" section of the project's grading rubric (available below).
•Week 7: You will complete Part III described above in the Project Overview section. This Week 7 deliverable will be graded with the "A Linear System of Equations (Part III)" section of the project's grading rubric (available below).
•Week 8: You will complete Part IV described above in the Project Overview section. This Week 8 deliverable will be graded with the "Reflection Statement" and "Reference List" sections of the project's grading rubric (available below). Note that to get full credit you will need to include a reference sheet which appropriately cites all sources used. Make sure to cite all sources used in Part I as well as those referenced in the Part IV reflection. Use APA format.

Question 496584: Hi! My daughter is working on linear patterns and has this problem amongst them. I understand the concept and the pattern but do not remember from my college days how to write the equation. Here's the problem as on her worksheet:
"Write an equation that describes each linear pattern."
X: 1 2 3 4 5 8
Y: 2 7 12 17 22 37
I have the equation figured out that Y= 4X-2 with the last number being a variable of 1 for each step. How does she write that in an equation showing the changing number?
My daughter did not bring her text home and the other sites that I've researched have the standard linear equations but I have been unsuccessful in finding this particular situation. Thank you soo much for your help!
Sincerely, Monica

Question 498210: I don't understand how to solve this problem?
Lars invested a sum at 5% and twice as much at 7%. If the total yearly income of the two investments is 760$, how much was invested at each rate? Please check.
thank you
